Analysis and design of multi-octave MMIC active baluns using a distributed amplifier gate line termination technique

The analysis and design of a multi-octave MMIC active balun is described in this paper. The technique employed uses the gate-line 'termination' of a distributed amplifier topology as a non-inverting output. Closed-form expressions for the two output signals have been derived. The MMIC prototype has achieved balun operation over 0.5 to 20 GHz with a 10/spl deg/ maximum phase error.<<ETX>>
